Definitions

  • the invention relates to centrifuges for domestic use, used for extracting juice from fruits, vegetables or the like.
  • the invention relates, more particularly, to a centrifuge comprising a tank intended to receive the centrifugation juice and in which is housed a basket comprising a perforated screen and a lower ring which is adapted to come to couple in rotation with a trainer integral with a motor shaft and which has a skirt extending downwards and outwards, the tank forming in its lower part a channel limited towards the driver by a circular flange extending upwards between the coach and skirt.
  • the role of the circular collar is to prevent the juice from reaching the motor by passing under the driver and through the opening for the passage of the shaft made in the base supporting the tank, and thus protect the motor.
  • this collar is not always as effective as it would be desirable. Indeed, during the high speed rotation of the basket, the juice tends to be sucked along the flange and there may be overflows, causing the engine large damage. It is moreover very difficult and expensive to adapt a seal at the level of the opening because of the high rotational speeds (approximately 12,000 revolutions / min).
  • the object of the present invention is to remedy this drawback and its object is to provide a device which prevents liquid overflowing over the collar.
  • the skirt of the basket has on its lower wall dynamic means intended to create, during the rotation of the basket, a current of air directed downward and towards the periphery of the tank, so as to retain the juice in the channel.
  • the present invention therefore has the advantage of using the reaction of the air on the dynamic means driven at high speed to create, during the rotation of the basket, a current of air which expels the liquid from the region of the collar and retains the juice at the bottom of the channel.
  • Figure 1 is a partial vertical sectional view of a centrifuge according to the invention
  • Figure 2 is a partial view of the bottom of the centrifuge basket
  • Figure 3 is a partial elevational view of a dynamic means consisting of a fin.
  • the centrifuge represented in FIG. 1 comprises a basket 1 comprising a perforated screen 2 and a lower ring 3 which is adapted to come to couple in rotation with a drive 4 secured to a motor shaft 5 which passes through a passage opening 6 made in a base 7 containing a motor (not shown).
  • the lower ring 3 of basket 1 has a skirt 8 extending downward and outward.
  • the basket is housed in a tank 9 intended to receive the centrifugation juice.
  • the tank 9 is removably supported by the base 7 and has an opening 10 for passage of the driver 4.
  • the tank 9 forms in its lower part a channel 11 limited towards the driver 4 by a circular flange 12 extending upwards between the driver 4 and the skirt 8.
  • the skirt 8 of the basket has on its lower wall 15 dynamic means 16 intended to create, during the rotation of the basket 1, a current of air directed downwards and towards the periphery 14 of the tank 9, so as to retain the juice in the channel 11.
  • dynamic means 16 are advantageously constituted by a series of fins directed downwards, each extending in a vertical plane in the vicinity of the periphery 17 of the skirt 8 towards the driver 4 and oriented in the direction of rotation F at an acute angle a determined born in relation to the tangent T at the periphery 17.
  • each fin 16 with the tangent T to the periphery 17 of the skirt 8 is between 30 and 40 degrees and preferably substantially equal to 35 degrees.
  • each fin 16 is made up of two contiguous parts, a first part 18 adjacent to the periphery 17 of the skirt 8, which has a substantially horizontal lower edge 19, and a second part 20 away from periphery 17, which has a chamfered lower edge 21, the inclination of which faces both the driver 4 and the first part 18.
  • This arrangement increases the air flow produced during rotation.
  • the driver 4 secured to the motor shaft 5 rotates at high speed the basket 1 containing fruit or the like.
  • the juice passes through the perforated screen 2 and falls into the channel 11 of the tank 9.
  • the juice tends to be sucked along the flange 12 then along the motor shaft 5 by suction effect created by the rotating parts of the engine.
  • the air flow produced by the fins 16 opposes this suction and drives the juice from the region of the collar 12 and retains it in the bottom of the channel 11 towards the periphery 14 of the tank 9, thus preventing the juice does not overflow the collar 12.
  • the flow of the juice through the outlet 13 is favored.
